Distributed Intelligence at the Consumer’s Premises
No full textThe concept of demand response or active demand has recently been introduced in several European projects. The key idea is that end-users play an active role in the electricity distribution process, adjusting their consumption patterns according to dynamic energy pricing policies. This chapter illustrates the functional and software architecture of the energy box following the scheme developed in the ADDRESS project. Moreover, an optimization model is presented for the scheduling of distributed energy resources (DERs) at consumers' premises. The chapter first provides descriptions of the EB functional and software architecture. Next, a classification of appliances, small generation devices and storage systems located at the end-user premises is given. The chapter also presents a mathematical model and a heuristic algorithm for the load scheduling problem solved by the EB. Finally, it illustrates the numerical results obtained from simulation experiments

No full textOn the Geometric Control of Internal Forces in Power Grasps
No full textThe geometric approach to the control of internal forces for robotic grasping is explored. Since the manipulation of deformable objects is a frequent occurrence (medical applications, manipulation of rubber and plastic in industry), manipulation systems with significant contact elasticity are studied. The presence of non-negligible compliance at the contacts, implies that the object dynamics cannot be neglected when attempting to control internal forces without affecting the object position. A geometric approach to derive a control law decoupling the internal force control action from the object dynamics is proposed
On the Decoupling and Output Functional Controllability of Robotic Manipulation
No full textThe problem of force/motion control in robotic manipulation is studied. A noninteracting control law of grasping contact forces and object motions is proposed.
In order to achieve force/motion trajectory tracking without transient errors, the output functional controllability of the controlled output is investigated. The frame-work throughout is the geometric approach to the multivariable systems. Numerical
examples are provided to show the eectiveness of the proposed control law
Noninteracting force/motion control of defective manipulation systems
No full textThis paper deals with the problem of noninteracting force/motion control for manipulation systems with possible kinematic defectivity. A geometric approach is adopted in the paper. The main result of the paper shows that a suitable choice of the outputs exists, for which a structural noninteraction property holds, and such that most practical manipulation tasks can be naturally specified
